Home work foy ch 23 1. A cork ball that is covered with conducting paint and charged to 4 × 10-10C is touched by an identical but un- charged cork ball; the balls then separate. This second cork ball is then touched by a third uncharged cork ball, and they separate. What is the charge of each ball at the end. and how many excess electrons does each ball have? 2. An electron and a proton attract each other with...
